I don't know how much PS3s cost nowadays, but if you are not buying one for gaming, I would wonder why the PS3 would be an option.
I have one of the early release OPPO BDP-83s. In addition to Blu-ray and the best up conversion for DVDs that I have seen, it does SACD, DVD-Audio, and HDCD. The sound quality is enough for me to remove three other players from my system.
Video quality for Blu-ray is outstanding. Video processing is handled by the same processor as is currently being used in the DVDO Edge.
At anywhere near $499, there is nothing that offers the combination of features and performance of the OPPO. It will very likely be available for the general public right about coinciding with your timeframe.
If you really want a PS3 for its gaming features, that's a different issue, but if you want the best audio and video available today in a BD player for up to 2-3 times the price of the OPPO, I suggest waiting for the OPPO release.
